An Israeli entrepreneur is selling kippas that blend into one’s hair, marketed to Jewish men who want to wear the religious garment without attracting undue attention from anti-Semites.

Shalom Koresh, a hairdresser in Rehovot, says the product will allow Jews to remain observant even in hostile places.

“The idea first came to me about six months ago,” he told Agence-France Presse. “I had customers coming in who had travelled in Europe and talked about growing anti-Semitism there. So I thought, why not make a kippa that blends in with the hair?”

Sold as the Magic Kippa, Koresh’s product is essentially a small hairpiece that sits atop the head and acts as an invisible kippa, the religious skullcap worn by many Jews and known as a yarmulke in Yiddish.

The 48-year-old Israeli says most of the demand for the Magic Kippa comes from France, Belgium and other European countries where there has been a marked uptick in anti-Semitic attacks and hate speech.

There were reportedly twice as many anti-Semitic acts recorded in France in 2014 than in 2013. Last year also set a record for the number of anti-Semitic incidents observed in the United Kingdom, according to a monitoring group. The prevalence of anti-Semitism in Europe is often linked to the Palestinian-Israeli conflict, and Israel’s war in Gaza in summer of 2014 may have exacerbated the problem.

In January, a gunman killed four Jewish hostages at a kosher market near Paris, shortly after two other terrorists stormed the offices of the satirical newspaper Charlie Hebdo and killed 11 people.
